CPU & Bandwith in test results

Hi team,

I am looking for solutions to improve page LCP.

Test with pagespeed insights alarms that we got ~1.0s on server response. I am not sure if upgrade the server and bandwidth would help.

The tech team said that CPU & bandwith utilization rate is so slow that there is over capacity in this respect.

While in the test result, utilization rate in the graph shows that CPU and bandwidth at some point reach its limit.

May I know the details about this CPU utilization and bandwidth in the test results? How is it calculated and what is it represent?
